Liu1 Experiment 8: Calorimeter ? the science of measuring Heat Objective: The objective of this experiment is to determine the specific heat capacity of an unknown metal and the heat of solution for the salt. Method: A calorimeter is a device used for calculate the enthalpy change of reaction, the science of measuring the heat of chemical reactions or physical change as well as heat capacity. The heat capacity of an object is the amount of heat needed to raise the temperature by 1K (or 1?C). The heat capacity of one gram of a substance is called its specific heat capacity.

Bio104 Laboratory ? Student?s Guide John Jay College, C.U.N.Y Lab #4 ? Page 1 Lab #4: Use of the Microscope; Bacteria and Protists I. The Domains of Life A. There are three major branches, or Domains, on the tree of life: Archaea, Bacteria, and Eukarya. B. It turns out that most of the living things on earth, comprising most of the biomass, are microscopic single-celled species! Today we will look at unicellular examples of two different domains: Bacteria and Eukarya. C. Protists are eukaryotes and most (but not all) are single-celled. However, some of the single-celled protest species can exist in colonies that resemble a multicellular organism, but this is not true

Conclusion 1) One error could be if the Magnesium did not heat all the way, then there were still solid pieces of Magnesium that could have made the mass greater. Extra mass in the crucible could cause the oxygen to be too low because extra mass would consume more space and would lessen the amount of space for oxygen within the crucible. 2) a. If you put more water in to the crucible than is needed for reaction 3, and did not wait for the excess water to dry out, then there would be to little oxygen. This is because the product in the crucible and the water would increase the amount of weight of the crucible/product as a whole and would leave little space for oxygen.
